Nick Jonas and Demi Lovato invited the entire staff of the Pulse nightclub to their concert in Orlando, and the event on Saturday included a tribute to the victims.
The two were joined onstage at the Amway Center by Andra Day for a stripped-down rendition of that singer's "Rise Up." Before the surprise performance, Jonas and Lovato welcomed a man named Hank to the stage who led a prayer for the 49 victims, plus the Voice singer, Christina Grimmie, who had been killed in Orlando before the mass shooting.
"Orlando, you've been through a lot," he told them. "In the last month, you've had two shootings, one of which was the most deadly shooting in all of America's history. So we want to pause in the midst of this exciting night... we can to pause and say a prayer, a prayer of healing."
